Answer #1

Answer A)

For finding association between gender and eye color, Chi square test is suitable. This is because both the variables are categorical.

Answer B)

For finding the effectiveness of training program, paired t-test is suitable. This is because in this case same test of same respondents is taken before and after seminar.

Answer C)

In this case, ANOVA is suitable as nurse wants to compare mean number of days for 3 groups (no health insurance, public health insurance, or private health insurance).
